WEATHER-STRIP.

$PECIFICATION forming part of Letters Patent No. 674,193, dated May 14, 1901.

Application filed February 25,1901. Serial No. 48,780. (No model.) 7

To alt whom it may concern.-

Be it known that I, SAM EL P. BRIOKER, a citizen of the United States of America, and a resident'of Allegheny, county of Allegheny, State of Pennsylvania, have invented certain new and useful Improvements in Weather- 'Strips, ofwhich the following is a specification, referencev being bad to the accompanying drawings, forming part of this specification, in which-- Figure 1 is a perspective detail view of a portion of the plow member of my improved weather-strip. Fig. 2 is a similar view of a portion of the tongue member. Fig. 8 is a cross-sectional view of a portion of a Window frame and sash provided with the interfitting plow and tongue members. Fig, 4 is a similar view showing a modified form of the tongue member. Fig. 5 is a perspective detail View of such modified form of tongue member. Fig. 6 is a view similar toFig. 3, but showing an amplification of the invention wherein a greater number'of i'hterfitting walls are employed. v V v My invention relates to'weather-strips, and

refers more particularly to interfitting (preferably metallic) devices for such purpose; and it consists in the form of construction and manner of operation as I shall now proceed to describe.

Heretofore metallic strips have been used in the formof tongues securedonthe'side of the frame and adapted to projetns into a cor- 1 responding plow or. groove'in the side of the sash-frame; but such devices are'only partially efficient, do not provide a tight fit, are notreliv able in continued operation by-reason of swelling or shrinkage of the Wood, causing the parts I 1 to bind, and other ca uses,and only imperfectly secure the objects in View. My invention has in view the use of both stationary and movable int'erfitting members,- so formedwith" relation to each other that they will provide a practically tight embracingsliding joint which will be maintained under all conditions.

' In the practice of my invention each member is formed of thin 'sheet'metal'bentinto form to provide the, inter-fitting members, which by reason of their double walls have sufficient'elasticity to insure the tight 611-,

' gagement which is desired. 7

Referring to the drawings, A represents the the bottom 4 of whichfis formed by the metal gether. The tongue member may be made by doublewall or tongue 6, having a rounded gained into the sideslO of the sash flushwith f.

or expansion will occur to insuresuchbin'd-f' thestrips that they shall be proportioned to tight interfitting joint and that? the results ment. It follows also that theposition of plow member, which is secured upon the inner sides of the frame by nails or screws, the member being made of a continuous piece of thin sheet metal of proper length, having the securing edges or flanges a a, and at the middle bent outwardly and back, forming the double Walls or ribs 2 2, having between them the intervening space 3, constituting the plow,

in substantial alinem'ent with the securingflanges a. The outer edges 5 of the walls 2 are rounded by bending of the metal, and while both sides of the walls are bent down close to each, other and are practically to gether there still remain considerable flexibility and elasticity,which is of great advantage when the interfitting members are tosimply doubling the metalover upon itself, as shown in Figs. 4 and 5, wherein the mem ber is referred to by letter B, providing a outer edge 7, adapted to be secured by nails in a suitable groove in the sash with'proper I I clearance, as shown, andto interfit between thewalls 2 of-the plow member. o In the formshown in Figs. 2 an'd 3 the tonguemember B is made in the same mm nor as to the middle wall 6; but themetal is I bent outwardly .again at the base offsuch middle wall or tongue, brought out to its M edge with intervening spaces'S, WlllOll'lLl turn embrace the double walls 2 of the plow mem. i ber,.and the metal is then flanged laterally, as at 9 9, providing means for attachment to the sash. "lhis form of' 'tongue member is t O terfit with'the plow member, as shown, and 1 formwith it a tight sliding weatherproofffitg I By reason of theelastic'nature of the in: ,1 7

terfittingmembers a sufficient compression the outer edge and when so mounted willinin'g fit, and care should be taken in, 1nakingeach other, so as to secure these res'ultsizf- It will be understood that as thusgconstructed the'- interfitting plow andtongue members will embrace each'otherand form a obtained are due to such int'erfittingengage f the members may be transposed with relation to each other, as by placing the plow member in the side of the sash and the tongue member in the frame, or that the number of the walls may be increased, as suggested by the arrangement shown in Fig. 6,without departing from my invention, since I do not desire to be limited to the form shown.

By my improved weather-strips all danger of warpage, shrinkage, or expansion of the wood is obviated, the objections noted are overcome, and a perfect, durable, and weatherproof strip is provided, which may be installed and left in during all seasons without interfering with the operation of the sashes. A further advantage of great importance is that all rattling or lateral movement of the sashes is entirely prevented by reason of the engagement of the stationary and movable members with each other. These advantages will be appreciated by those accustomed to the use of weather-strips, and it will be understood that I do not desire to be confined to the exact construction shown and described, but that variations therefrom may be made by the skilled mechanic without departing therefrom.

Having described my invention, What I claim is- 1. In a Weather-strip, the combination of a plow member provided with extended double sides formed of a continuous metallic sheet, and an interfitting doubled-tongue member.

2. In a weather-strip, the combination of a plow member made of a continuous metallic sheet formed into double side walls with an intervening space and a tongue member formed of a doubled strip, interfitting between the side walls. a

3. In a weather-strip the combination of a plow member having a plurality of extended doubled sides formed by bending the metal upon itself, withan intervening space between the sides; and a tongue member having one or more double tongues adapted to interfit between such doubled sides.

4. As an improved article of manufacture, a weather-stri p consisting of a metallic plate provided with a plurality of extended doublesided longitudinal ribs with an intervening space between the ribs.

5. As an improved article of manufacture, a weather-strip consisting of a metallic plate provided with a plurality of extended doublesided longitudinal ribs, with an intervening space between the ribs, and means for securing the strip in position.

6. As an improved article of manufacture, a weather-strip consisting of a metallic plate bent into a double-sided central longitudinal tongue, with redoubled sides and intervening spaces, and means for securing the strip in position.
